[MacRuby-devel] Computer Serial Number

[Terry Moore]

There is no BridgeSupport for IOkit... so ruby is out for now.

like Henry said you can escape to a shell.. or wrap this snippet in an objc class...

#include <CoreFoundation/CoreFoundation.h>
#include <IOKit/IOKitLib.h>

// Returns the serial number as a CFString.
// It is the caller's responsibility to release the returned CFString when done with it.
void CopySerialNumber(CFStringRef *serialNumber)
{
    if (serialNumber != NULL) {
        *serialNumber = NULL;

        io_service_t    platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault,
                                           IOServiceMatching("IOPlatformExpertDevice"));

        if (platformExpert) {
            CFTypeRef serialNumberAsCFString =
                IORegistryEntryCreateCFProperty(platformExpert,
                                                CFSTR(kIOPlatformSerialNumberKey),
                                                kCFAllocatorDefault, 0);
            if (serialNumberAsCFString) {
                *serialNumber = serialNumberAsCFString;
            }

            IOObjectRelease(platformExpert);
        }
    }
}

"Looks like I talked too fast, there isn't any BridgeSupport file for IOKit, 
even in Preview 2. I will look into it, as I'm planning to roll out a new 
version soon.
